The first completely recyclable stand-up pouch of a monomaterial (polyethylene) with a removable wrap-around label (also of polyethylene), designed according to the Cradle-to-Cradle® Principle, is a joint development of Werner & Mertz and the packaging and paper company Mondi.
“With this groundbreaking design for recycling, we have taken a giant step toward closed-loop circulation of plastic packaging,” said Sander. After use, the patented innovative stand-up pouch can be recycled 100 percent into recyclates of nearly the same quality as the raw material.
This innovation is the fulfillment of an idea which has long been on the Werner & Mertz agenda. “Back in 2014 we at Werner & Mertz were looking for ‘single-material concepts,’ said Sander. The goal was a pouch of monomaterial – instead of the usual multi-layer product – which could be printed and filled by using existing technologies. It quickly became apparent that the goal could be achieved only in cooperation with a packaging specialist, Sander added. Werner & Mertz found exactly that in Mondi. “Nowadays it is hardly possible for just one company to come up with such an innovation on its own. It takes a network to develop packaging for the circular economy,” said Thomas Kahl, Project Manager EcoSolutions from Mondi Consumer Packaging. “And we – Mondi and Werner & Mertz, were prepared to take up the challenge.”
